我想通過ajax請求創建登錄頁面,但現在面臨的問題,當用戶輸入錯誤的密碼我希望它仍然在同一頁上。併成功登錄它跳轉到下一個頁。如何重定向多個位置取決於JSON.stringify(響應)
$('#login').on('click',function(event){
event.preventDefault();
var username = document.getElementById("username").value;
var password = document.getElementById("password").value;
if(password == ''||username == '')
{
alert ('Please fill the fields!');
}
$.ajax({
url: "api/learnapi.php",
type: "get",
dataType: "json",
data: {type: "login",email:username ,pass:password},
//type: should be same in server code, otherwise code will not run
ContentType: "application/json",
success: function (response) {
alert(JSON.stringify(response));
location.href ="app-student-dashboard.php";
},
error: function (err) {
alert(JSON.stringify(err));
}
});
});
但是當輸入正確或錯誤的密碼時,它會跳轉到app-student-dashboard.php,我該如何阻止它這樣做。這裏是我的驗證用戶
$loname = $_GET['email'];
$lopass = $_GET['pass'];
$query1="select * from signup where email='$loname'";
$result1= mysqli_query($conn,$query1);
$row = mysqli_fetch_array($result1, MYSQLI_ASSOC);
// printf ("%s \n", $row["password"]);
$pass1=$row["password"];
if($pass1 == $lopass) {
$res["flag"] = true;
$rest["message"] = "Login successful.";
}
if($pass1 != $lopass)
{
$res["flag"] = false;
$rest["message"] = "Wrong password entered.";
}
代碼是這可能調用錯誤:功能(錯誤)從那裏發送消息「輸入錯誤口令」。
我如何使成功的條件。我嘗試如果(響應==真正),而不是重定向到下一頁 – oceanier
@oceanier就是這樣,給我投票,如果它有幫助。謝謝! – dadan
